Neither are easy on a remote and poorly-known planet. How deep is "deep"? 50cm? 50m? 500m? 5km?

it gets astronomically more expensive to go ever deeper, especially when we don't understand the composition of the subsurface and it's resitance to drilling, and the nature of any voids and fluids.

I'm sorry that we can't get instant gratification but it's going to take a lot of effort, learning, and a few mistakes before we can drill deep on Mars.

But don't let that that stop us trying. A polar ice-penetrator is relatively easy, for instance. Good stratighraphy of the polar caps will result from that.

Regarding, "instant gratificaction":

"I'm sorry that we can't get instant gratification but it's going to take a lot of effort, learning, and a few mistakes before we can drill deep on Mars."

Dear, Nick, gratification regarding Mars has been anything but. You know that, BUT, gratification is what we're all striving for and you know what I mean... it means finding traces of water and even microbial life in our lifetimes.

I know, Nick, but you know, it's not just the "polar caps" that I'm interested in or better yet 'the so-called experts'. --~~Evidence of ancient water on Mars does not only exhist at the polar caps... please.~~------

Honestly, I'm glad that NASA will be looking at Mawrth.

We're not looking for instant gratification, just.... JUST gratification. Aren't you?

"Poorly known planet", hardly.
